Question:
Brandi solved 
by using a related multiplication expression. What multiplication expression did she is?
Answer:
The related multiplication expression is 
.
Solution:
Given expression is .
We can write 5 as a fraction with denominator 1.
Using the fraction rule 
,
Now multiply the fractions using the rule 
,
Let us multiply the numbers in the numerator and denominator separately, we get
Hence the related multiplication expression is .
The parametric equations for x and y describe a circle of radius 10 m, so the length of the base of the fence is the length of the circumference of a circle of radius 10 m. The formula for that circumference (C) is ...
... C = 2πr
... C = 2π·(10 m) = 20π m
The height as a function of angle (t) is found by substituting for x and y.
... h(t) = h(x(t), y(t)) = 4 + 0.01·((10cos(t))²-)10sin(t))²) = 4+cos(2t)
The average value of this over the range 0 ≤ t ≤ 2π is 4, since the cosine function has two full cycles in that range, and its average value over a cycle is zero.
Thus, the area of one side of the fence is that of a rectangle 20π m long and 4 m wide. That will be
... (20π m)·(4 m) = 80π m²
The amount of paint required to cover both sides of the fence is
... 2×(80π m²)×(1 L)/(10 m²) = 16π L ≈ 50.3 L

You can work out the integral for area as a function of t. When you do, you will find it gives this same result.
Answer:
l = (S/pi)-r^2
Step-by-step explanation:
Just rearrange the equation.
S = pi*l + pi * r^2
S-pi*r^2 = pi*l
l = (S-pi*r^2)/pi
l = (S/pi)-r^2
Answer:
The scale factor is 3
Step-by-step explanation:
The reason is that 12, 15, and 9 equal 4, 3, and 5 if divided by 3
